DEFLECTOR ARRANGEMENT FOR BUILDING VENTILATING AND COOLING SYSTEMS.

Application led March 11, 1926. u Serial No. 93,818.

This invention relates to improvements in deliector arrangements forbullding ventilating and cooling 'systems and'it consists of the mattershereinafter described and more particularly pointed out in the appendedclaims.

The installation of Ventilating and cooling systems in theaters andother places of large public gatherings for supplying fresh air at thedesired temperature thereto, is most necessary to meet the ublic demand.The placing' of the disc arge mouth of the system, is in many instancesdetermined by the general outla of the building with the result thatsaid mouth cannot always be laced in the position `for most eilicientistribution of the air.

In some theater installations, it is only possible to place thedischarge mouth down near the floor near one side wall.. With the usualdeiiectors now employed, it is not possible to direct the moving a1r sothat it will be distributed evenly over the entire auditorium of thetheater.

The primary object of the invention is to provide a deflectorconstruction for such systems, which will direct the moving air for thebest distribution thereof no matter where the discharge mouth may belocated.

A further object .of the invention is to rovide a defleetor embodyingtwo sets of v ouver boards or vanes, with the boards of one setarranged-at a right angle to those of the other set whereby the passages35 defined thereby are disposed in the direction it is desired todeiiect the moving air.

These objects ofthe invention, las well as others, together with `themany advantages thereof will more fully appear as we proceed with ourspecification.

Inthe drawings Fig. 1 is a typical section through a portion of atheater building in the ventilation s stem of which is embodied ourimprove deiiector construction.

Fig. 2 is a view in front elevation of the discharge mouth of aVentilating system embodying our improved deiector construction, withthe louver boards arranged in a different manner from that shown in Fig.1.

Fig. 3 is a horizontal section as taken onthe line 3-3 of Fig. 2.

Figs. 4 and 5 are diagrammatic views tangular casing open at its frontand rear discharge mouths due to di erent building v conditions.

In Fig.' 1 we have illustratedthe fan room 1 as located'beneath thestage 2 of a. theater, building 3. In the fan room the front of which isformed by an upright wall 4, is located the cooling and ventilating fancasing 5, the fan of which is driven by an electric motor 6. In the wall4 is located the deflector 7 the rear end of the casing of which isconnected by a canvas connection 8 with the discharge end of the fancasing 5. The inlet for the fresh air into the fan room may be pro.vided by an o ening 9 in the rear wall of the theater an in which anysuitable kind of closure devices may be employed, said inlet beingconnected to the fan room by a duct 10. The deiector 7 includes a recandset in an opening in the fan room wall 4 and which casing comprises sideboards 11-11 and top and bottom boards 12 andv 13 respectively. Saidcasing is usually of a depth greater than that of the wall and is-provided with a plurality of sets of louvers or deflector vanes 14 and15, and herein termed the front and rear sets of louvers or defiectorboards respectively. As best shown in Figs. 2 and 3, the front louversare disposed vertically and the rear louversl are disposed horizontally.The front louvers are spaced a desired distance apart and are mclined.toward one side and the rear endI of the casing at an angleapproximating 30 while the rear louvers are spaced the same distance.apart and are inclined downwardly and forwardly at the same angle. Thelouvers ma be made of thin wooden boards or of meta lic strips of suchrigidity as to amply resist vibration under .the action of the airpassing through the 'deflector casing. The ends of said louvers may befixed in their respective casing boards in any suitable manner and inthe case of wooden louvers, blocks or strips 16 are nailed t0 the casinboards and the louvers engage upon sai blocks and are likewise nailedthereto. vSo that the louver boards will not ap ear too conspicuous, thefront of the de ector casing may be covered with a suitable grating 17,of such open mesh as to neonata in no way interfere with the passage ofthe air current therethrough.

ln Fig. Il is illustrated a diagrammatic plan view of a theater building3, or the like wherein the deflector 7 is positioned in the stage wallthereof and near the floor and adjacent one side wall. Under suchconditions it is apparent that with a deflector casing having only oneset of louvers or delectors, the moving current of air could only bedeflected either in a horizontal plane or in a vertical plane andtherefore there would be dead air pockets in certain parts of thetheater' and an overabundance of air in certain other parts thereof.lll/lith out improved deflector in place, the louvers would be soassembled inthe dellector casing as to direct the Current of air notonly away from the adjacent wall but also upwardly away from the floorand over toward the diagonally opposite corner as indicated by thearrows 18 in said figure, which current would also be deflectedupwardly. ,ln this manner the entire Volume of air within. theauditorium would be caused to move to circulate.

In Fig. 5 is shown a diagrammatic vertical section of a theater building3 looking toward the stage 2 and wherein the delector 7 is placed abovethe proscenium arch and to one side the center thereof which would bringthe deflector casing quite a distancev above the floor. Under suchconditions the sets of deliectors would be so positioned as to deflectthe air downwardly and laterally as indicated by the arrows 19 and thusinsure the maximum of ventilation and this without any localized drafts.lt is to be understood that the stale warm air, displaced by theincoming fresh oool air, passes up the stacks or ventilators (not shown)to the outside atmosphere. It is to be understood that after the placeof location in a theater building is known, the louvers are positionedin the detlector easing to meet that particular location in which thedeflector is to be installed. l

Our improved deiector is indeed simple in construction and is etlicientoperation for its intended purpose-"lt has no moving parts requiringattention and there is nothing to get out of order.

While in describing our invention, we have referred to certain detailsof meehanical construction as Well as form and arrangement of the partsthereof, the same is to be considered as by Way of illustration only,and not by way of limitation exceptv as may be pointed out in theappended claims.

Ne claim as our invention:-

l. A Ventilating and cooling system including a fan and casing thereforhaving an inlet and an outlet, a detlector casing, operatively connectedto the outlet of said fan casing, and a plurality of sets of deliectormembers in the detlector easing, with the members of one set arranged atan angle to those of the other set.

2. A Ventilating and cooling system including a fan and casing thereforhaving an inlet and an outlet, a rectangular dellector casing havinginner and outer sets of deflector members with the deflector members ofone set extending at a. right angle to those of the other set, themembers of both sets beingpitched at substantially the same relativeangle. v

3. A deilectoi` for a ventilator system including an open front and reardeflecter casing comprising upright side members and horizontal top andbottom members, inner and outer sets of spaced detlector members in thecasing, with the members of one set extending parallel with the sidemembers of the casing and with the members of the other set extendingparallel with the top and bottom members of the casing, the de- Hectormembers in each set being inclined at an angle to the plane in whichthey are located.

In testimony whereof, I have hereunto set my hand this 27th day ofFebruary, 1926.
